TOTALIZING MECHANISM.

Specification of Letters Patent.

Patented Mar. 14, 1922.

Application filed February 13, 1918. Serial No. 216,955. 7

To all whom it may concern:

Be it known that I, \VALTER E. Hoscn, a citizen of the United States, residing in the city of St. Louis and State of Missouri, have invented new and useful Improvements in Totalizing Mechanism, of which the following is a specification.

This invention relates to counters or totalizing mechanism. The general object of the invention is to produce a very simple mechanism for counting or totalizing, and

oneofthe novel features resides in organizing the parts in such a way as to facilitate the setting back or return of the counter wheels to their zero position. Such totalizing mechanism usually includes carrying mechanism associated with the counter wheels to effect the carrying from the wheels disconnected from the counter wheels.

Further objects of the invention will appear hereinafter.

The invention consists in the general combination of parts and simplicity of details to be described hereinafter. all of which contribute to produce a simple and efiicient totalizing mechanism.

In the drawing which fully illustrates the tentmeans for preventing accidental movement of the carrying mechanism when it is disconnected from the counter wheels;

Figure 7 is a vertical section showing the details of :1 Geneva stop movement which I may employ as part of the carrying mechamsm; T

Figure 8 is a vertical section showing in detail the manner in which the driving pinion of the carrying mechanism drives its corresponding counter wheel;

Figure 9 is a vertical section through one of the carrying mechanisms; and

Figure 10 is a fragmentary vertical section illustrating my novel returning means for returning each counter wheel to its zero position.

Referring more particularly to the parts, 1 represents the frame of the machine which comprises a pair of vertical frame plates 2 and 3 connected by a plurality of horizontal frame bars 4. The counter wheels 5, 6 and 7 are rotatably mounted in a coaxial relation, that is to say, they are loosely rotatable on an arbor 8 fixed in the framei (See Figure 5). These wheels are of different denomination, for example, the wheel 5 may be employed to indicate fractions of the unit of measure, if the totalizer is used in conjunction with a measuring machine. That is to say, if employed for measuring cloth, it is convenient to have the wheel of lowest denomination indicate eighths of a yard. In that case, the wheel 6 would indicate units of yards and the wheel 7 would be the 10s wheel. lVhile I have only-illustrated two wheels of higher denomination, it should be understood that there may be as many of these higher denomination wheels as desired.

The carrying from each wheel of lower denomination to each wheel of higher'denomination is effected through the agency of a carrying mechanism 9 corresponding to each higher denomination, and these carrying mechanisms are supported in such a way that they normally form a driving connection between the wheels which they connect. At each revolution of the wheel of lower denomination the wheel of next higher denomination will be advanced through one number space. The carrying mechanisms are m'ovably mounted, however, so that they may be moved in such a way as to disconnect them from the counter wheels, thereby permitting the counter wheels to be independ ently rotatable; while in this condition the counter wheels are returned by the" returning mechanism to their zero position. In disconnecting the carrying mechanism the drive to the wheel of lowest denomination is also disconnected, so that this wheel may be also returned with the other counter wheels to its zero osit-ion.

In or er to accomplish these results I employ a movable frame 10 which com.- prises a plurality of carrier arms 11', there being one of these carrier arms to correspond with each of the carrier mechanisms and these carrier arms are rigidly attached to a rock shaft 12 rotatably mounted in the frame 1. A similar arm 13 is provided. rigid with the rock shaft 12, and this arm carries a pinion 14 which meshes with a gear wheel 15 mounted to rotate with the wheel 5, that is to say, in the present case this wheel 15 is rigid with the wheel 5. I provide means for driving the pinion 14 so as to advance the counter wheels. For this purpose I provide an idle gear 16 which is driven by a pinion 17 rotatably mounted on the rock shaft, and this pinion 17 is rigid with a gear wheel 18 which may be driven by a gear wheel 19 (indicated by the dotted outline) from any piece of mechanism, for example, a cloth measuring machine.

The counter wheels 6 and 7 are provided with rigid gear wheels 20 and 21 which are similar to the gear wheel 15 and these gear wheels are rotated periodically through one number space by means of pinions 22 and 23 with which they mesh respectively. These pinions 22 and 23 constitute parts. respectively, of the two carrying mechanisms 9. One of these mechanisms is shown in longitudinal section in Figure 9. Any suitable carrying mechanism may be employed. I have illustrated a very Simple form involving the use of a Geneva stop movement. I shall now describe the mechanism located between the wheels 5 and 6. which co-operates with its carrying mechanism 9 to effect this carrying movement. and it should be understood that this mechanism is duplicated between the wheels 6 and 7. Referring particularly to Figure 5, on the hub 24 of the wheel 5 there is rigidly secured. a sleeve 25, the end portion of which is formed into a Geneva disc 26 (see Figure 7). said disc having a single tooth 27. This tooth co-operates with a Geneva stop wheel 23 having a plurality of tooth spaces 29 which are engaged in succession by the tooth 27 as the disc 26 revolves. Between these periodical advances of the wheel 28, this wheel 28 is held against rotation by one of the concave faces 30 held against the periphery of the disc 26. This Geneva stop wheel 28 is rigid with its corresponding pinion 22 and rotatable on a pin 11 on the end of its supporting arm 11. Its periodical advancing movement is imparted through pinion 22 to the gear 20 and the counter wheel 6.

The means for disconnecting the carrying mechanisms from the counter wheels consists of a lever 31 which is rigidly secured to the rock shaft 12. By moving this lever in the proper direction evidently the arms 11 and the arm 13 will move away from the counter wheels and leave them free to rotate independently on the arbor 8.

In order to prevent the carrying mechanisms from moving accidentally when they are disconnected from the counter wheels, the parts 22 and 28 carry a rigid detent wheel 32. (See Figures 6 and 9). This detent wheel may be in the form of a starwheel having a plurality of concave recesses or notches 33. In one of these notches a roller 34 lies. said roller being carried by a small arm 35 pivotally mounted at 36 on its corresponding arm 11, and pressed into engagement with the notch 33 by a small wire spring 37. I provide means for normally holding the arms 11 and 13 at the proper distance from the counter wheels to maintain an efiicient driving connection with the gear wheels of the counter wheels, and the other parts. For this purpose the rock shaft 12 is provided with a rigid stop plate 38 which is pulled upwardly by a spring 39 (see Figure 4). the upward movement of the plate 38 and the arms 11 being limited by means of a stop pin 40 which is received by a slot 41 in the stop plate. If it were not for this. the pinion 22 would be pressed so forcibly against the gear 20 as to impede its free rotation.

In' order to effectthe return of the wheel 5 to its zero position. associated with the wheel is a returning cam; to this end the sleeve 25 is formed at one end into a returning cam 42. (See Figure 3). This cam 42 is eccentric on the axis of rotation and is formed with a peak 43 on one side of its axis of rotation, and on the opposite side of the axis is formed with a notch or depression 44. This depression is nearer to the axis than the peak. Corresponding to this cam 42 I provide returning means in the form of an arm 45. on the side of the counter wheels opposite to the carrying mechanisms: when the movable frame 10 is moved to disconnect the carrying mechanisms. this returning means or arm 45 moves up against the edge of the cam 42. On account of the construction and form of the cam, when the roller 46 carried on the arm 45 presses against the cam it will rotate the cam 1n one direction or theother; this ro-- tation will continue until the roller 46 seats itself in the depression 44. This is the zero position of this counter wheel. In order that the presure of the roller 46 against the cam 42 shall be a yielding pressure, the pull upon the'arm 45 is exerted through a spring 47, the other end of which is attached to the corresponding arm 11. Between the wheels 6 and 7 a similar arm 48 is provided, carrying'a roller 49 which cooperates with a similar heart-shaped cam 50 which is rigid with the hub of the wheel 6. The arms 45 and 48 are rotatably mounted on hubs 51 rigidly attached to the rockshaft 12 and areheld in place by the arms 11 which attach to the ends of the hubs. The arms 45 and 48 seat against collars 52 on the hubs and there is a pin and slot connection between the arms 11 and the arms 45 and 48, respectively, (see Figure 3), in which 53 represents the pin carried by the arm 11, and 54 represents the slot in the arm 45. With this construction, evidently, when the arm 45 moves in toward the counter wheel after the roller 46 comes against the cam 42 the spring .47 will extend and yieldingly hold the roller 46 against the cam. This arrangement is desirable because it enables allof the returning arms to maintain engagement with their corresponding cams at the same time, that is to say, one cam could not prevent the other cams from being engaged by their arms.

Substantially the same arrangement is adopted for returning the 10s wheel 7 (see Figure 4), in which 55 represents the returning arm which has a pm and slot connection 56 with the stop plate 38. the spring 57 being employed to connect the arm 55 with the stop plate.

In practice the mechanism described above may be mounted infa suitable case, with a window opening extending over the counter wheels in such a way that only one numher on each counter wheel is visible through the window. This case and window have been omitted in the drawing to facilitate the disclosure of the invention.
